Install Tenable Core on Hardware

You can install OT Security Sensor directly on Tenable-provided hardware using an .iso image. When you install Tenable Core via an .iso image on your computer, Tenable Core replaces your existing operating system with the Tenable Core operating system.

Note: Tenable Core currently supports two host operating system options: Oracle Linux 8 (OL8) and CentOS (EL7).

Before you begin:

  • Confirm your environment will support your intended use of the instance, as described in  System and License Requirements.

  • Confirm your internet and port access will support your intended use of the instance, as described in Access Requirements.

  • Confirm that Tenable Core + Tenable OT Security was not preinstalled on your hardware for any new instance of Tenable Core + Tenable OT Security. Not all new instances require manual installation.

To install OT Security Sensor on hardware:

  1. Download the Tenable Core Tenable.ot Sensor Installation ISO file from the Tenable Downloads page.

  2. Boot the .iso. For more information, see your environment documentation.

    Caution: Booting the .iso replaces your existing operating system with the Tenable Core operating system.

    Tip: To monitor the progress of the installation, select Install TenableCore using serial console from the boot menu. For more information about the OT Security serial console, see the OT Security User Guide.

    The installer installs OT Security Sensor on your hardware.

  3. The installation begins if there are no configuration errors.

    The Installation menu appears if there are configuration errors (such as errors after setting up a Base Repository, for example):

    Lenovo M90n-1

    The installation runs and the server restarts.

What to do next:

  • Continue getting started with OT Security Sensor, as described in Get Started.
